WATER HEATER.

Application led November 11, 1924. Serial No. 749,173.

This invention relates to improvements in water heaters for hot water systems the present embodiment relating more particularly to the base or burner carrying portions of such hot water heaters used in such systems.

The invention further relates to the form and arran ement of the -bottom portion of the heater body or jacket, together with an improved form of burner carrying base adapted to be quickly attached to or detached from the body of the heater and to swivel on the latter when attached, the improved swivel base being of particular advantage in connecting up or leading in the gas conduits oi' connections from any angle to the mixer or Bunsen burner portion of the base, asdistinguished from the ordinary hot water heater Where the point of gas inlet or connection is relatively fixed.

The invention further relates to an improved detachable swivelly connected burner supporting base embodying integral Bunsen burner and drip pan members adapted to readily receive and support a suitable burner within the base portion of the water heater body or jacket.

l/Vith the above mentioned and other ends in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described, illustrated in one of its embodiments in. the accompanying drawings, and particularly pointed out in-t'he appended claims.

Referring to the drawlngs, forming a part of this specification, Figure 1 is a fragmentary central vertical sectional view of the base or burner portion of a hot water heater constructed in accordance with this invent-ion. l

Fig. 2, ahorizontal cross sectional View,

, taken on line 2-2 of Fig. l, a portion of thc burner head being broken away for the pur- .poseof clearer illustration of the subjacent parts. y

Similar numerals of reference designate like parts througlint all the figures of the drawings. i

The heater body or jacket is preferably of general cylindrical form-and comprises, 1n ythe present instance, a relatively fixed section l, of general semi-cylindrical form, and a, relatively movable or hinged section 1a provided With hinges l, adapted to be openedsections 1 and l outwardly for affording access to the interior water heating coils 1m and burner head 4 when occasion arises.

The heater body or jacket made up of the is provided with an open bottom adapted to removably receive and contain the burner and burner supporting base and drip pan, hereinafter referred to.

y As a means of quickly attaching or detach-v ing the Supportingbase, and particularly as a means of' circumferentially shifting or swivelling the supporting base for bringing the Bunsen burner or gas inlet mixin pipe to variable positions for the purposes erein mentioned, a swivelling connection or joint between the heater body and burner supporting base is provided;

As a means .of providing such swivel joint or connection, the base of the heater -body or l jacket. The upper face 21 ofthe recess 2b is angula-rly disposed with respect to the face 2, When the parts are in assembled or nested relation, it will be seen that ythe flanged rims 1b and 2a interlock with each other and will permit the supporting base and connected parts to be rotated or swivelled relatively of the heater body or fixed section l of the jacket.

As a means of removably securing or attaching the supporting base 2 in assembled relation, and particularly as a means of permitting such base to be swivelled or adjusted relatively of the fixed section and of holding such swivel base in interlocking swivellin relation to the fixed section when the hin ed or door section lJL is open, an internal ug le, is provided, said lug 1e being preferably provided with a recess or pocket 1f, adapted to receive the upper end of a clamp plate 3, extending downwardly to engage the inn'er periphery of the flanged rim 2a of the supportm base, said clam 3 being removably and a Justably secured y means of a clamp screw or bolt 3 and a nut 3", the latter being preferably seated in a nut receiving recess or pocket 1g, on the exterior portion of the relatively fixed section 1 of the jacket. The angular relation of the Contact portions 1h and 21 of the rims lb and 2a exert a wedging action upon each other when they vare clamped together and serve to hold the heater casing and base in rigid engagement with each other in the desired position.

" The swivel base, in the present instance,

' swivel is provided with an integral Bunsen burner, mixer or gas supply pipe 2d, terminating at the center of the swivelling base in an upwardly extending tapered inlet or hub portion 2", for convenient attachment to the hub or head portion of a suitable burner head or body 4. The swivel head is also preferably provided with an integral drip and evaporating pan 2f, connected or suspended, in the present instance, by means of radially extending arms 2. In the present instance, the supporting base 2 is provided with a de ending skirt or rim portion 2h, the latter eing provided at suitable intervals with supporting legs 2*. As heaters of this general type are generally supported or suspended at one side of the storage or hot Water t-ank and.' some distance above the base or door line, it will be understood that the legs 2* are merely used for temporarily supporting the heaters when in storage or unattached in the heating system. Under these conditions it will be apparent from the construction of the base that the heater casing willbe supported by the raised border 2Jn of the supporting base 2., B reason of the above construction it will be o vious that the swivel base may be turned circumferentially by moving 'from right to left, using, for example, the projecting end of the Bunsen burner or mixer pipe 2.d as a handle so thatv the inlet pipe or connection to the gas inlet or mixer tube portion of the burner may be lined up at any convenient angle'to the gas pipes previously installed.`
